GLASSWORKING MACHINERY.

Application filed January 1, 1927. Serial No. 158,432.

My present invention relates to glass working machinery and particularly to machinery for applying a rotating flame to glass to be'worked.

Various objects and advantages of the invention will be obvious from the following particular description of forms of apparatusembodying the invention or from an inspection of the accompanying drawings; and the invention also consists in certaln new and useful features of construction and combinations of parts hereinafter set forth and claimed.

In the accompanying drawings there is shown for purposes of illustration one form of apparatus embodying the invention, in which Fig. 1 is a front elevation view,

Fig. 2 is a side elevation view and Fig. 3 is avertical mid section new looking from the front.

In the drawings the table 1 carries the fixed hollow cylinder 3 whose central open ing registers with the opening 5 through said table. Extending through the bore of said cylinder 3 is the cylinder 6 which is rotatable and slidable longitudinally therein.

Said cylinder 6 has formedv at its upper end the annular flange 8 having an annular channel 10 formed in the lower surfaces thereof. About said cylinder 6 and having its upper surface bearing .agalnst thelower surface of said flange 8 is the collar 12 which is held in position by the springs 14, 14 bearing against the lower surface of said collar at their lower ends and at the upper ends bearing against said cylinder 3, pins or rods 16, 16 are threaded into the lower surface of said collar 12 and extend onelthrough each of said springs 14, 14 and into a corresponding hole 18, 18 extending downwardly from the upper surface of said cylinder 3 to such a distance as to permit considerable longitudinal movement of said cylinder 6 in the bore of said cylinder 3. These pins 16, 16 serve to hold said springs 14, 14 in position and also to prevent rotation of sald collar 12 when said cylinder 6 is rotated. In

the lower surface of said collar 12 and in the upper surface of said flange 8 are provided registering annular channels 20 and 22 respectively. An opening 24 formed through said collar 12 at one end connects with said channel 22 and at its opposite end connects with the flexible hose 26 which which extends through and below said table 1 is provided a pulley 42 over which passes the belt 44 driven by the motor 46 whose starting and stopping and whose speed can be regulated byla foot or: hand control not shown. Said pulley 42 is keyed to said cylinder 6 through a sliding keyway 48 formed in said cylinder 6 and the bracket 50 supports said pulley 42 and permits the movement of said cylinder 6 along its axis through said pulley 42. At its lower end said cylinder 6 carries an annular flange 52 havingv an annular channel 54 formed in the lateral surface thereof. The fork member 56 pivoted to the table 1 by the bracket '58 'carries a pairof dogs 60, which extend into said channel 54 at diametrically opposite, points. A foot treadle (not shown) connected to said member 56 and operating against a tension spring serves to actuate said member 56 to raise said cylinder 6 longitudinally through said cylinder 3.

A bracket '70 under said table 1 carries the support member 72 which extends upwardly through the central opening 74 in said cylinder 6 and terminates above said flange 8 in the uppermost position thereof and below the converging point of .fiames fromsaid gas jets 40, 40. At its upper end said support 72 carries a pair of fork members 76 and 78. On said member 76 is pivotally mounted the V block 80 and on said member 78 and opposite said block 80. is

' pivotally mounted the-V block 82 on the pin 84 which is slidable in said member 76 and which carries on its outer end the handle member 86. A spring 88 mounted about pin 84 between block 80 and said-member 76 serves to move said block 80'toward said block 82 for clamping a piece of work therebetween. In the drawings is illustrated a mercury switch having a glass envelope 90 positioned between said V blocks 80 and 82 and having a tabulation 92 extending from the upper surface thereof. A gauge 94 in the form of a hook pivoted at one end to the cross bar of said fork member 76 and 78 and having the turned over end 96 extending inwardly toward saidblocks 80, 82 serves-to position said switch and tubulationbetween said blocks 80 and 82 in predetermined relation to the point of convergence of the flames from said jets 40, 40. A rod 98 connected -to said hook or gauge 94 at its, pivot serves through thehandle portion 100 to move said member 96 into and out of gauging position a with respect to? a switch body between said blocks 80, 82. In the use and operation of the embodiment of the invention herein illustrated and above described, a piece of "of said jets 40, IO-to bring them to desired position against said tubulation to cause the melting. of the glassthereat, upon which the tubulation may be drawn away and the glass envelope sealed off without the tubulation.

In the raising and lowering of said cylinder 6 and the attached parts, through said foot treadle and its said spring (not shown) said annular flange 52 serves as a stop against said bracket 50 for limiting the upward movement of said cylinder 6 and the attached parts. i

It is tobe understood that the present invention can be applied in machines and apparatus for handling glassware other than that used to illustrate the'invention and for performing operations other than those described for purposes ofillustration and example. The invention is not limited to' ma chines which have parts rotatable upon vertical axes, nor because the-gases of rotation and of the rotatable parts can be inclined or can be horizontal as in a lathe type of machine. I

And the invention can be applied for dif ferent kinds of machinery for blowing or other working of glass.
